Charging by Friction

As it is explained, that all of the objects are made of different types of atoms and combination of different atoms. The presence of atoms give objects electrical behavior one of thee properties known as electron affinity, this behavior is referring to the amount of attraction force of one electron for one another, which is one of the process of charging, that is charging my friction or well known as rubbing.
For example of the charging by friction, balloon that is rubbed with our hair, the electrons that are stable in the balloon will be attracted to the ones in our hair, or it can be opposite that the electrons from our hair is attracted to the ones in the balloon, since either of the objects has lose or gain electrons, they will be more attracted to each other because the one that loses electrons, will become positive charge and the one who gained electrons will be negative charged. For example if we put then close to each other, the balloon will move and will be closer to our hair or the hair will go up to touch the balloon.

Frictional charging is a process that transfers electrons to the other object by rubbing them together, if one of the objects has greater attraction force, then the object will take the electrons of the weaker force. For the object that gains electrons will have excess of electrons and become negative charged because the number of electrons is too much and the one that loses becomes positive since the amount of proton is greater.
